FELIX OORPELET AND ALBERT DUPRF, OF ROMILLY, FRANCE.

HOSlERY-MACHINE.

SPECIFICATION forming part of Letters Patent No. 713,609, dated November 18, 1902.

Application filed February 23,1899. Serial No. '706A84. (No model.)

To all whom it may concern:

Be it known that we, FELIX OORPELET and ALBERT DUPRF, citizens of the Republic of France, residing at Romilly-sur-Seine, in the department of Aube, France, have invented certain new and useful Improvements in H0- siery-Machines and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

These improvements, which may be applied to any type of straight-bar knitting-machine in which ribbed or plain fabrics are produced, have for their object to permit the production in unlimitedlength of those parts of the knitted fabrics at the ends of ribbed tops, ribbed hose and half-hose, plain hose, and other articles, which consists of a folded-over or flap part knitted into the fabric along its edge, so as to constitute a doubled part called the welt.

By the existing method of manufacture the welt consists of a very few rows of plain fabric knitted upon the frame needle-bar, into which a welt-wire is inserted by hand after the first rows of welt are knitted. The weltwire then has weights hooked upon each of its ends to pull upon the work until the completion of the welt, when the wires are withdrawn.

According, to the presentimprovements, the welt-wires are removably attached by their ends to a pair of parallel chains or flexible bands, to which positive motion is communicated from the machine-shaft. In their travel the welt-wires have to pass between the needle-bars, and it therefore becomes necessary to provide means for their separation.

The accompanying drawings illustrate in what manner this invention may be carried into effect and will be hereinafter referred to.

Figures 1 and 2 represent sectional side views, and Fig. 3 a partial plan. Figs. 4, 5, and 6 are diagrams representing the engagement of the welt by the welt-wires. Fig. 7 is a perspective view of a machine embodying our improvements. Fig. 8 is a front elevation of the left-hand end of the machine shown in Fig. 7. Fig. 9 is a cross-section on line 8 8, Fig. 8.

The essential portions of the new apparatus consist of means for separating the needlebars for the passage of the welt-wires, for moving the chains carrying the Welt-wires, and automatic means for maintaining the weight constantly at about the same height from the floor.

A series of Welt-wires a 0., spaced at distances apart having relation to the lengths of the welts to be produced, are held by any suitable means-as, for example, by the endless pitch-chains b b or their equivalent-and are removablyconnectedtherewith by any known convenient devices.

At the commencement of the welt the weltwire approaches, and to enable it to pass into the welt the needle-bars are separated. For this purpose a cam A is fixed upon the automatic welt-wheel. During the production of the welt the welt-wheel moves, carrying with it the cam A, which thus acts upon the lever B, which is fulcrumed at D and carries on its opposite ends the friction-rollers c 0. Because of the shape of the cam, which will vary according to the type of machine to which these improvements are applied, the lever when acted on by the cam first moves outward at its lower end. It consequently moves in the opposite direction at its upper end, where its friction-roller c exerts a pressure upon the lever F, fulcrumed at G. This pressure compels the opposite end of the lever F, which is beveled,to rest upon the angle-iron H, fixed to the shaft J of the machine needlebar. The pressure being exerted gradually, the beveled end of the lever F draws the shaft of the machine needle-bar toward the front of the machine. The space thus obtained suffices for the passage of the welt-Wire. The welt-Wire having passed, the welt-wheel continuesits movement, carrying with it the cam A, whereupon the lovers move in the reverse direction and cause the displaced needle-bar to resume the working position. The weltwheel also carries a second cam K, which by the movement of the wheel acts upon a lever L, fulcrumed at D and carrying at its upper end a click M, engaging with the ratchetwheel R, fixed upon the machine-shaft N. Under this condition the ratchet-wheel is immovable, and since it is fixed upon the weightdriven machine-shaft, which drives the weltwire chains, 2. stoppage of the movement of IOO the wires ensues so long as the ratchet-wheel is held by the click. The length of action of the cam is calculated in such a manner that the stoppage may be obtained for the length of time necessary to knit one-half of the walls of the welt. The cam K having passed, the click leaves the ratchet-wheel, and the shaft N thus becomes free again.

The diagram Fig. 4 shows the commencement of the welt to with the welt-wire approaching at a. As the knitting of the welt proceeds the machine needle-bar is moved away from the frame needle-bar, as already described, to permit the passage of the weltwire into the welt, as indicated by the diagram Fig. 5. The diagram Fig. 6 shows the welt after it has been closed and with its welt-bar imprisoned in it and pulling the work by its connection with the chains 1) b. A counterweight T, suspended from the cord V, tends to turn the machine-shaft N by means of the grooved pulley X, to which the cord is attached, and the two ratchet-wheels Y Z. The ratchet-wheel B, being no longer held by the click M, the machine-shaft N, on which the pulley X is mounted and to which it is indirectly secured by being engaged with the ratchet-wheel Z, keyed upon M, is subject to the pull of the counterweight and turns, moving with it the welt-chains and welt-wires by means of chain-wheels R R, also keyed upon the shaft N, as shown by Fig. 3. The advancing chains introduce the Wire a into that part of the fabric constituting the welt produced during the stoppage, and from this moment the tension of the fabric is produced by the motion of the chains derived from the counterweight and transmitted through the welt-wire imprisoned within the welt. When the fabric is completed, it can be separated by making two strokes without moving the thread carrier, so that during these two strokes no fabric is produced. After the separation thus effected the welt-wire is Withdrawn, the fabric removed, and the welt-wire is replaced on the chains.

The automatic means for maintaining the weight T constantly at about the same height from the floor consists of the grooved pulley X, the cord V, the stop 5, lever 6, connectingrod 7, lever 8, connecting-rod 9, click 5, engaging with ratchet-wheel Y, and the spring 10 and click 4,engaging with the ratchet-wheel Z. The ratchet-Wheel Y and the pulley X are fixed together; but both are mounted free upon the shaft N. The click 4 is pinned upon the pulley X and held in gear by the spring 10. The pulley-wheel X receives its motion from the weight T and in advancing pulls along the click 4, fixed to the grooved pulley X, and this click, which engages the ratchetwheel Z, produces rotation of the shaft N, on which Z is fixed, and consequently motion of the chains 1) b, which, through the imprisoned welt-wire, produces tension and exerts a pull upon the fabric. It follows that as the length of the fabric produced increases the weight T must tend to descend to a certain extent; but immediately upon the development of this motion of the weight the end of the lever 6, which rests upon the stop 3, connected with the weight, moves downward, and consequently through the agency of the parts 7, 8, and 9 brings the click or dog 5 into engagement with the teeth of the ratchet-wheel Y, which is then rotated by the continuous reciprocation of the dog 5, which is suitably actuated by connection with some moving part of the machine until the weight has by this means been again so far raised that the stop 3 has once more lifted the lever 6, and thus once more put the click or dog 5 out of action. The ratchet-wheel Z, fixed upon the shaft N, is independent, except through the click 4 of the grooved pulley X and the ratchet-wheel Y.
